General :: Linking Front End With Multiple Back Ends
Sep 30, 2014
My question encompasses a front end connected to multiple back ends. It is probably a mundane point, but reading a few articles didn't seem to touch on it.
By this, let me toss out that I am thinking of the personnel where I work when I say 95% have a hard time using email and MS Word, let alone mundane functions like find a file, etc. As such, I have to make my front-ends extremely user friendly.
With that in mind, when developers have multiple back ends, what are thoughts about the best way to relink when required? Even when there are 'more sophisticated' users? Security not an issue or is an issue (inasmuch as can be handled in access)?
Ex: Large corporation with a multitude of user ability. Large database with say 3 different back ends.
I was thinking about keeping a front-end table with each table name and UNC path, hard coding paths to corresponding table names, etc.
Personally I don't have a need for multiple back-ends, but the question came up while reading.

Hi guys,
I need help with security settings and that. I have a database which i want available on a shared server. Basically i only want people to beable to see one form but not beable to see anything else or make any changes to this form.
Do i need to split and make a front and back end? I will want to make occasional changes to tables etc.. and so would want this to automatically update on the database seen by everyone else.
Sorry, not making much sense but am bit confused about it all!
Any help from some clever peeps?

I did a search in here as well as Google to figure out why when I relinked the front end to the back end after adding 2 tables to the back end that the tables did NOT show up on the front end. Only the original tables that I began with.From what I have read there are different ways to do it. One suggestion on here was to create the table on the front end and export it to the back end. I guess I will have to do this going forward.
But my question is, after searching pages upon pages with no luck, since I already have the tables in the back end how do I tell the front end to find them and link them?

For the company I am doing my thesis, I developed a tool in MS Access for monitoring sales data, customers, employee data etc…
The tool is working with a front-end database, installed locally on every PC and a Back-end on the company’s server ( Located at city Genk)
The tool is working smooth on the location in Genk.
But then the problem occurs when this tool had to be used on an other company location, 100km from the server (Antwerp); the waiting and loading times are very long, even for the smallest data.
Obvious this is because the companies network from one location to another is too slow. But because of financial reasons I’m looking for a software solution.
An idea is to create a Back-end server for each location, for all local data and one general back-end server for unique data ( for instance: there has to be a unique calculation number for each calculation made in the entire company).
I think this will decrease waiting times for some data, but not all…
Or does anyone have an other idea?

I have (on a company network) a FrontEnd .accde and a backend .accdb - currently ~ 10 users (some over wifi - slow!)The FrontEnd is becoming a rather large file ~ 10 MB and is also becoming slower.I am looking to separate this in to 3 FrontEnd files as to simplify and to lessen the file sizes etc.
My question is - are there any issues around a 3 x FrontEnd databases all connecting to 1 x backend database holding all the tables - over a network?

How do I hide or disable the File tab in Access 2010 on my front ends?
The file tab being present allows end user to get into Privacy Options and Printing. Printing is okay if I could disable the Privacy Options for end users, then it wouldn't matter if they have access to the File Tab.
Possible very serious security issue!

I had posted this in another area but didn't receive a response and my whole project has ground to a halt until I sort this out :(
I have made a database with front and back ends. Now I wish to be able to use the front end over the Internet but the IP address of the back end keeps changing weekly because of my ISP.
Now I have made a splash screen at the start of the program which asks for the IP address and when this is entered the front end links to the back end - but I can't get the code right for this
The code I have at the moment is embarrasingly wrong so I'm not putting it up here
The code I have at the moment has a box that asks for user to enter the IP address - I need it to use the IP address to enter the database at ip//data.mdb
Regards, James

Access 2010
Objective?: I'm attempting to change the file location of the back end portion of my split database.
What I've done so far: I've used the linked table manager to update the back end location of all tables in the front end portion of the database.
Symptoms: When making a change to the OLD back end: If I change the name or move the old back end and then try to re-open the front end, Access opens as if I'm opening the application itself without any database associated with it until I restore the OLD back end to its appropriate state.
When making a change to the NEW back end: If I change the name or move the new Back end and then try to re-open the front end, I get a: "Could not find file" error message until I restore the new back end to it's appropriate state.
I've just discovered a query that I think put me one step closer to resolving this issue. [URL] .....
When I run this query:
Code:
SELECT MSysObjects.Database
FROM MSysObjects
GROUP BY MSysObjects.Database, MSysObjects.Type
HAVING (((MSysObjects.Type) In (4,6)));
It returns 2 results:
1. The path of my old back end
2. The path of my new back end.
Unfortunately I'm not able to update the values from the Datasheet, but this does confirm to me that the old back end is still some how being used by the front end even after my tables have all been updated.

Using Dropbox to host a split database. Ulimately I would like to create a run version for users with the back end held in a drop box directory.
As an unsplit database everything is working fine on dropbox records are saved in a timely manner and great.
Once I split to FE /BE only some records are saved on the BE and some are dropped. Was getting conflicted copies of Back end but manged to stop this happening but the records were noit on either copy.
Gave each user their own FE (on a drop box directory) linking to a BE in a sub directory on the same dropbox.
The key issue is that not all users have access and I don't want them to get into code so want to aim towards a run version.

I have a Database that has been split into two.
Back-end for all the data.
Front end for all the forms and queries.
The front end has been saved in a accde format and distributed to 20+ users. They have all saved this onto there computers and this is used as an application.The users complete a form on a weekly basis on the application and then save. This then saves into the back end.For some reason I have noticed that a few users submission randomly do not save. For the life of me I cannot understand why.All users have saved them into the back end in the past but every now and then submission for users do not save.

I have a small system that consists of a back end data base and 2 front ends. having 2 front ends was a historic reason but they cover 2 distinct processes in the system.
I now have the need for using the same module(s) in both front ends. Each has a copy which is fine if nothing changes but when it does I have to apply the changes made (or copy over in its entirety) from one front end to the other.
Although this is no big deal I can forsee it slipping through the net.
Can 2 front ends access the SAME module and if so how?

I have split my database in Front End och Back End, and both are password protected. The Front End has been converted to ACCDE.
When I try to import to Excel from Front End and/or Back End using database connections I receive a message telling me that I am using an invalid password (even though I use the same password when I encrypt/decrypt FE and BE). I've tried using Access import, ODBC and Microsoft Query. (In some cases I 'm also prompted to set a username, which I do not know which it should be since I haven't set one in my database (except the automatic "admin"))
How do I go about to make this work?

Have a database with a back end that I have been working on. The database resides on a USB at the moment. I was ready to deploy and now when I try to re-link the back end tables, I repeatedly have the following error: "Your network was interrupted. To continue, close the database, and then open it again."
At first I thought this was something to do with the network, as I was moving it to a shared network drive. However, I can recreate the same issue using someone else's computer and using my USB (although it's mapped to a different drive letter). I've tried a few things, including recreating the back end by importing only the table structure, but still no luck.

I have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?

Currently the system where I work is set up so that everyone has their own front end on the local network. I would like to change this because updating all of them takes a lot of time for me and skill level for users is too low for me to trust them with updating it on there own.
My question is this:
If I were to create a shortcut on everyone's desktop that linked to one front end would this be wise? I can't seem to get a straight answer from anywhere on the internet. I know most places say that it is better to have the actual front end on the staffs computer but that would make my job of keeping the database updated even worse because staff have multiple computers and this isn't my full time job.
If this is okay practice how many users would this be able to sustain? Currently we only have 6 users on the database with there own front end and it works great. I am planning on adding around 10 more users in the future but if needed they could have there own database as they are separate programs.

I've prepared a front end database with forms that allow data to be keyed into linked tables to my main databse.
However, currently the front end database only allows 1 user to do it at 1 time and when another user tries to open the file, an error "The Database Has Been Placed in a State by User on Machine That Prevents It From Being Opened or Locked'
Is there anyway to allow multiple users to use the front end database at the same time?

Hi friends,
I think I am having some problem with my back end and frond end files. I have a mde file that anytime I enter new data or change some things in the old clients file, it does not update on the mdb file. Anytime I need to change forms or report or any thing at all, I am suppose to copy the BE file and the MDB file to my workstatio, remove the table link, make the changes I want to make on the design mode and then import the files back to the live copy of the mdb file then make another mde file to work with. But When I copy the BE and the MDB files, I don't have the updated client list or new client just added. So as not to affect other users, I can not make changes in the MDE file and even the MDE file will not even let me make any changes in design mode. I don't know If I am making sense but any help will be appreciated
thanks

I am having a trouble with a multiuser DB. I have split it using the Splitter Wizard and have put a copy of my FE to a second computer and relinking its tables. When I opening the bound form in computer 1, computer 2 can not open that form and sometimes computers lock and had to restart the machines. But if I open that form in computer 2 first and then the same form in computer 1 , it works fine. I have set full sharing to computer 1. I am using Access 2007 and Windows VISTA.
Both have FE, the BE is located in a shared folder with full permissions in C: in computer 1, the FE of computer 1 is in that same folder. Both computers are connected via a Cat5e Cable.
FE in computer1 table links to c:databaseBE and computer 2 links to computer1_IP_Addressc:/databaseBE
Can anyone help me please!!!
I'd appreciate it a lot
Thank you!!

Hi there, :cool:
I've one FE & BE related question here. Ok first of all I've BE in server and each user have copy of FE in local PC. But I've one problem with linked tables between FE & BE.
Is there a way that FE can programmatically create connection to BE linked tables or user is able to link those tables manually, if FE can't find/connect to linked tables in BE? Or do I just have to manually configure each users FE linked tables?
All replies are welcome and well approciated at all costs! :D

Hope this isn't too silly, but I've just discovered "decompile". Instructions don't mention back ends and front ends. Do you have to run decompile on the FE and again on the BE, or is it sufficient to do it only on the FE (which has links to tables in the BE).
Cheers,
Christine
